Blue Screen STOP: 0x0000007B

I am getting blue screen like this:

What i actually did is I marked my system partition as active, when restarted, I had message

"BOOTMGR is missing Ctrl + Alt + Del to restart"

I inserted Windows 7 Ultimate x64 CD and started Startup Repair. After it has finished I restarted and got this blue screen.

Any ideas (except new instalation and formatting the disks) that might help?

This BSoD error means: INACCESSIBLE_BOOT_DEVICE

You can try the following method to fix it, but if this doesn't work, chances are high you'll need to reinstall windows.

During startup, press F8 repeatedly until you get the startup menu which also lists boot into safe mode.

In this menu, you'll find the option Restore to last configuration known to work (or something similar.

It should fix your problem, but may undo the changes you made.
